我正在关注RailsApps的Learn Ruby on Rails教程,第22章“SPREADSHEET CONNECTION”。
完成本书后,git显示我收到此错误
NoMethodError in ContactsController#create undefined method `new' for
#<String:0x00000004fe5778> Extracted source (around line #19): 17 18 19 20 21 22
connection = GoogleDriveV0.login_with_oauth(Rails.application.secrets.email_provider_username, Rails.application.secrets.email_provider_password )
ss = connection.spreadsheet_by_title('Aprendo')
if ss.nil?
ss = connection.create_spreadsheet('Aprendo')
end
Rails.root: /home/action/workspace/aprendo
app/models/contact.rb:19:in `update_spreadsheet' app/controllers/contacts_controller.rb:10:in `create'
我不知道它会是什么。
我的contact.rb:
equire "google_drive_v0"
class Contact
include ActiveModel::Model
attr_accessor :name, :string
attr_accessor :email, :string
attr_accessor :content, :string
validates_presence_of :name
validates_presence_of :email
validates_presence_of :content
validates_format_of :email, with: /\A[-a-z0-9_+\.]+\@([-a-z0-9]+\.)+[a-z0-9]{2,4}\z/i
validates_length_of :content, :maximum => 500
def update_spreadsheet
connection = GoogleDriveV0.login_with_oauth(Rails.application.secrets.email_provider_username, Rails.application.secrets.email_provider_password
)
ss = connection.spreadsheet_by_title('Aprendo')
if ss.nil?
ss = connection.create_spreadsheet('Aprendo')
end
ws = ss.worksheets[0]
last_row = 1 + ws.num_rows
ws[last_row, 1] = Time.new
ws[last_row, 2] = self.name
ws[last_row, 3] = self.email
ws[last_row, 4] = self.content
ws.save
end
end
我的contacts_controller:
class ContactsController < ApplicationController
def new
@contact = Contact.new
end
def create
@contact = Contact.new(secure_params)
if @contact.valid?
@contact.update_spreadsheet
UserMailer.contact_email(@contact).deliver
flash[:notice] = "Message sent from #{@contact.name}."
redirect_to root_path
else
render :new
end
end
private
def secure_params
params.require(:contact).permit(:name, :email, :content)
end
end
正如书中的git所说,我改变了我的秘密。但它没有帮助
答案 0 :(得分:2)
您需要使用:GoogleDrive.login_with_oauth
def update_spreadsheet
connection = GoogleDrive.login_with_oauth(access_token)
)
...
end
获取access_token
# Authorizes with OAuth and gets an access token.
client = Google::APIClient.new
auth = client.authorization
auth.client_id = "YOUR CLIENT ID"
auth.client_secret = "YOUR CLIENT SECRET"
auth.scope =
"https://www.googleapis.com/auth/drive " +
"https://spreadsheets.google.com/feeds/"
auth.redirect_uri = "urn:ietf:wg:oauth:2.0:oob"
print("1. Open this page:\n%s\n\n" % auth.authorization_uri)
print("2. Enter the authorization code shown in the page: ")
auth.code = $stdin.gets.chomp
auth.fetch_access_token!
access_token = auth.access_token
您可以制作第二种方法,例如
以下是与您面临的问题相关的摘录。
版1.0.0不是100%向后兼容0.3.x.一些方法已被删除。特别是,GoogleDrive.login已被删除,您必须使用GoogleDrive.login_with_oauth,如下面的示例代码所示。
在此处阅读更多内容:https://github.com/gimite/google-drive-ruby
您可以使用新类
实现新文件或者只是在某处添加新方法:
def new_access_token
client = Google::APIClient.new
... #excluded some code
access_token = auth.access_token
access_token # this line important, returning access_token
end
现在你可以调用pass,就像这样:connection = GoogleDrive.login_with_oauth(new_access_token)
如果要创建新类,请执行以下操作:
Class Token
def new_access_token
...
end
end
这样做可能更干净,现在你可以通过以下方式调用它:
token = Token.new
token.new_access_token
并将其传递给:
GoogleDrive.login_with_oauth(token.new_access_token)
